HA 구성
DeepFinder HA 구성
DeepFinder Manager는 Server와 PostgreSQL의 HA(고가용성) 구성을 지원하여, Active 서버 장애 시 Standby 서버가 즉시 동작하도록 설정할 수 있습니다.
HA 구성이 완료되면, Active 서버에 장애(네트워크 단절, 고장 등) 발생 시 Standby 서버가 Active 서버로 자동 전환되며, Agent들 또한 Standby 서버로 통신을 재요청합니다.
Server Process HA 구성
1) 설치 파일 다운로드
리포지토리에서 DeepFinder Manager Server 설치 파일을 다운로드합니다.
[root@localhost~]# wget http://download.deepfinder.co.kr/DeepFinder/dfServer/DFServer.tar.gz2) 압축 해제
다운로드한 설치 파일의 압축을 해제합니다.
[root@localhost~]# tar xvfz DFServer.tar.gz3) 스크립트 실행
압축이 해제된 DFServer 디렉토리로 진입하여 설치 스크립트를 실행합니다.
[root@localhost~]# cd DFServer
[root@localhost~]# ./setup.sh

1. modify config.xml
2. cp license.txt /usr/local/dfserver/license/
3. service dfserver startServer Active 설치
[root@localhost DFServer]# ./ha.sh master 192.168.3.8
Redirecting to /bin/systemctl restart dfserver.service
Server Standby 설치
[root@localhost DFServer]# ./ha.sh slave 192.168.3.58
Redirecting to /bin/systemctl restart dfserver.service
Postgres HA 구성
1) Postgres 포트 오픈
Active 서버와 Standby 서버 간의 PostgreSQL 통신을 위해, 각 서버의 방화벽에서 TCP 5432 포트를 Inbound로 허용합니다.
Danger
Inbound 5432 포트 개방 시, 반드시 상대편 서버의 IP에 대해서만 허용하도록 보안 정책을 설정하십시오.
2) Postgres Active 서버 설치
[root@localhost DFDB]# ./setup_postgres.sh master

The files belonging to this database system will be owned by user "postgres".
This user must also own the server process.

3) Postgres Standby 서버 설치

4) pg_hba.conf 수정
Active/Standby 서버 간의 PostgreSQL 통신을 허용하기 위해, 양쪽 서버의 pg_hba.conf 파일을 각각 수정해야 합니다.
각 서버의 pg_hba.conf 파일에 상대방 서버의 IP 주소를 host 항목으로 추가합니다.
수정 후에는 dfserver-postgres 서비스를 재시작하여 변경 내용을 적용합니다.
[root@ip-172-31-12-31 ~]# cat /usr/local/dfserver/postgres/data/pg_hba.conf
# TYPE DATABASE USER ADDRESS METHOD
# "local" is for Unix domain socket connections only
